get a terminal-bash-shell…

apt-get install libgtk-3-dev; # install gnome3 header files
mkdir -p /projects/c/guigtk+; # create project directory
cd /projects/c/guigtk+; # enter project directory
vim gnome3gui.c; # create new file

# fill it with that content

#include <gtk/gtk.h>

static void activate (GtkApplication* app, gpointer user_data)
{
  GtkWidget *window;
 
  window = gtk_application_window_new (app);
  gtk_window_set_title (GTK_WINDOW (window), "Window");
  gtk_window_set_default_size (GTK_WINDOW (window), 200, 200);
  gtk_widget_show_all (window);
}

int main (int argc, char **argv)
{
  GtkApplication *app;
  int status;

  app = gtk_application_new ("org.gtk.example", G_APPLICATION_FLAGS_NONE);
  g_signal_connect (app, "activate", G_CALLBACK (activate), NULL);
  status = g_application_run (G_APPLICATION (app), argc, argv);
  g_object_unref (app);

  return status;
}

# compile it, should work without errors

gcc `pkg-config --cflags gtk+-3.0` -o gnome3gui.bin gnome3gui.c `pkg-config --libs gtk+-3.0`;

./gnome3gui.bin; # run it

result is:

gnome3 gtk first gui application

CONGRATULATIONS!

YOU JUST CREATED YOUR FIRST GUI APP ON LINUX GNOME3! 🙂
